I think this is way too dangerous. I played a lot with ECN in the past (and fixed number of bugs in linux) and discovered many times I had to disable it to be able to surf the Internet. I am kind of an expert so always could figure out what was the problem, but average user wont have the choice. Reverting might take a long long time, it wont help people stuck behind buggy equipment. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
